To all whom imay concern:

Be it known that We, ALPHA R. Best, sind An'ron Hnrrni., citizens of theUnited States, and residents of Rochester, in the county of Monroe undState ot New York, have invented certain new und useful Iniprovements inHollow Columns, of which the following is o specification.

This invention relates to hollow columns, and consists in theconstruction hereinafter set forth.

The object of the invention is to produce s built-up column that Will bepractically es strong as a solid column, and unaffected by changes ofhumidity or temperature.

ln the drziwingsz-Figure l is :t crosswseotion of o part of o.y eoluinnconstructed in accordance with this invention, in the proeess ofassembling; Fig. 2 is u. similar crosssection of :1 column whencompleted; l 3 is :L partial view of a column, showing onohulf insection and the other half in exterior elevation; Fig. 4c isI suelevation ot s whole column, drawn on s reduced scale; and Fig. 5 is opartiel cross-section, showing a modification.

' The column is built of the blocks or stoves l, shown in the usueltruncated torin. fit suitable intervals, und at corresponding hei'hts,perforations 2 are inode through eocli block or stove, und through euchset of said perforatious (which are in oline nient) :1 wire 3 is passed.Suid Wires are bent into circuler forni, and ure sprung open at theirends to enter the perforotions il es aforesaid. lil/'lien the iullnumber ot' blocks or stoves luis been strung on the wires 3, the endsot' the latter :ire overlapped through one or more of seid blocks orstoves, and the Whole structure is pressed tightly together in the usuelmanner. ln one of the blocks or stoves l ureV holes 4; (Fig. l)eounterbored to moet the perforutions 2. Soft metal or o. composition,or some other essily fusible metal, is introduced, in u molten orviscous condition, into the holes 4, and runs, or is forced it notsulicientiy viscous to ilow freely; thence around through all of theperoretions 2, forming, when it solidifies, u solid block or ring 5. inwhich is embedded the Wire 3, thus rigidly (zonne-oting the blocks orstoves. As the material 5 hai-dens, t'shrnks slightly, und draws theblocks or stoves very tightly together. No glue is used. lTheinequalities in the joints through which may be filled with putty orWnite leed, onif desired, the abutting faces of the blocks or stoves maybe covered with white leed liefore they are drown too-ether.

ln the construct-ion snown, the Wires 3 here near their ends one or moreoffsets or bends '6, that serve to hold them more firmly in the material5. lt should also be noted the,u in this construction the connectingineens :ire it being the aperture il, which may be plugged so that itbecomes practically in visible.` A column thus eonstructed een be turnedand shaped in e lathe utter the blocks are secured together. Fig. l,shows them before thej,Y lieve been shaped, and

2 after that hss been done. y

ln the modification. shown iu 5, the wire 3 is represented es consistingt1 ports 3a ond 3, that overlap Ywithin the blocks la, preferablyopposite the hole the nietnl introduced.

The ivire 3 is separated order to allow for the e" pension of thebloolts. To provide :tor the return ogn-in of the 'Wires to theirinitial position on contraction, their ends are overlapped and each ispassed through plete Z thot lits end closes the transverse periorstionin the bloeit llf. Heads 8, 8 or. the wires 3"', 3a, respectively,prevent th ir being Withdrawn fron. the plates i", Y. Both plates srolocated, erslolv, within tl; seine blocks, and sp1-1. o; f.) tendsnorinslly to s rrete thorn, so when the blocks expend, the crossed endset the wires 3, 3 are drawn in. oppos directions and the plates on tl;ir brought nearer together, against tir snee of the spring. ln seinearticles me inode according to this `luveifition, i expansion undeontruc'tion nifty be eo; ersble, it is advisable to introduce this Jing link-in the il/That.

6. The combination witlr a seletional column having a continuousperforation through the sections, extending transversely to theirjuncture, oi' a metallic rod, upon which said sections are threaded7 andthat has a yielding link consisting of a compressible spring 9 betweenplates 7, 7, on overlapping ends of the rod; and a block of easilyfusible metal, east in place around said rod and filling saidperforations; substantially as shown and described.
